MOTU 896 MK3 Windows 10 dropouts

I had my system working fine with Windows Vista 64bit (quad core pentium, 6gb ram, Sonar X1 Producer, ASIO drivers) running MOTU 896 MK3 FW with an MUADIO 8 channel mic pre connected via ADAT lightpipe.  After upgrading to windows 10 I am experiencing dropouts during playback.
 
For a test I try to play the the Sonar tutorial AUDIODEMO.CWP and it (usually) plays fine.  However, there is another sample project that is full of midi sequences and keyboard parts that I can't play at all without dropping out, stuttering and skipping.  I also recorded 8 channel audio (8 drum mics) and tried to play it back and I also get a bunch of stutters, skips etc., though they occur at different parts of the track, so I'm assuming the problem is with the playback and not the recording.
 
I've gone through every "optimizing windows 10" type thing I can find and nothing seems to fix it.  I've changed every recommended parameter that seems to affect playback and still nothing.  I've also re-installed the latest MOTU driver using their Audio Installer that says it will install the latest driver.  (I also find a thread on how to removed old versions of the driver that may be lurking.) No luck.
 
Going by everything I've read, it seems Windows 10 should offer good performance for Digital Audio, but I can't get this system to work right.  Again, this exact setup worked flawlessly before under Vista.  The only change is the OS (windows 10) and the new drivers for the MOTU.
 
Anyone have any ideas on what I can check?
 
Thanks!

Did the legacy driver help? There was a non-obvious step in the install, pretty sure I wrote it down since I need to apply it to my DAW in the studio. I'll look for it when I wander down there.

You can get the legacy driver using the links specified in here: https://support.microsoft.com/en-us/kb/2970191
 
The MS installation steps don't work though, you need to do what I did because in Win10 the install doesn't result in the new driver being added to the list of available drivers for some reason. 
 
OK, I'm done yapping. I hope this helps. 

Thanks, eric.  I just read your posts.  Trying it now!

So, I just installed the legacy drivers and no good.  I've got a PCIe SIIG card as well.  Like I said, this exact setup was working previous under Vista.
 
I did manage to playback 10 track of recorded audio without a dropout, but when I try to play the Sonar demo, "moonbeams...", a bunch of MIDI tracks, it drops out and squeaks its head off.
 
I guess I have to keep trying.
 
Thanks!

Dang! For me the legacy drivers were the silver bullet! Win 10 drivers would not even talk to the presonus, it didn't even see the mixer.

It'll be odd if it turns out to be the legacy driver - maybe he has motherboard-based Firewire ports?  

That wasn't it, but if it had been I would not have been surprised. I have four PCs at home with TI based firewire cards and all of them only work with the Legacy driver. If I use the Windows 10 driver I cannot get them to transfer video without dropouts. It always seems to be a crapshoot.

Hmm...FWIW - device manager here reports that the SIIG card I'm using has a VIA OHCI Host Controller.
 
Apparently, it's using the stock Microsoft Windows provided driver, version 10.0.10586.0, dated 6/21/2006.

Hmmm ... If you managed to get the Legacy Driver installed correctly then the Control Panel's IEEE 1394 Host Controllers section should have "1394 OHCI Compliant Host Controller (Legacy)" as the device, there would no longer be a mention of VIA.

 
It would be helpful if the OP went into device manager and pulled up which driver his system reports it's using.
